2 (ill whom imply concern: v Be it known that I, Or'ro PETERMANN, a

citizen of the Republic of Switzerland, and

' a resident of Groton, county of Tompkins,

Q r formed from sheet steel or ot-her metal and State of New York, have invented certain new and'u'seful Improvements in Type- WYriting-Mac-hine Constructions, of which the following is a. full, clear, and-exact description; I

This invention relates more particularly to the construction of the frame and car ria-geof typewriting'machi'nes in which the carriage is adapted to be shifted'or moved into compact typewriter? v p "One object of the invention is to provide a, frame and carriage which may be! stamped relation to another part of the in'such a way as to be strong, lightand at tractlve n, appearance, and which frame may, be so made' that it isadapted to have of manufa'cture;

Other objects of the invention are to provide a simple and easily constructed frame 3g 7 made of a single piece of'sheet metal and inin which. approximately the entire frame is which only the transverse or bracing bars are made independent-thereof; to provide -simple and. efiicient transverse bars and means for attaching the same to the sides of the machine frame; and to provide the frame'with means whereby the type-bars may be "properly supported on a part thereof.

A further object.- of the invention is to provide means whereby the frame may be constructed to form a supporting and guiding mcans 'fo-r a part of the platen-shift mechanism; and as a means to support a- {partof-theesoapement mechanism.

With these and other, objects in v'iew, the invention" will. be hereinafter more par tacularly described with reference to the ac-" companying drawingsywhich form a part of this specification, andwill then be pointed out inthe the' end of the descr ipjtion.

While I show the 'invention 'as applied .more particularly to a type of machine in which the carriage and bed arefolded over into overhanging relation th the keyboards,

"it will ,be understood that the invention may be applied to-other forms of typewritingmachines and may be constructedto adapt it for such purpose without departing from the nature of the invention.

The machine may be provided with any suitable mechanism. As shown,{ a plurality of transversely-extendmgrods l0 arearranged between the sides of the frame.- and a suspended ,on these rods are the key-levers 11, the innerends of which are connected by links 12 to the type-bars 13. These typebars have-heads 14 on which may be ar ranged a plurality of characters indicating the upper and lower case typegervthe. figures or other characters asis usual in typewriting Ina-chines. Arranged above the frame vat-ed and mounted on the support is a bed 16 on which is adapted to .move a carriage 17, and on said carriage lr is supported the platen 18 The support 15 may be foldable or arranged in any other desired way, andsaicl-supportmay be car "led by the bars'or slides 19, the lowerends of which are adapted to be operatively connected to one or more shift levers 20. Only one shift lever is shown and this is pivotally held to a transverse rod 21 so that when said the desired extent. The parts thusfar described, with the exception of the frame and is'a support 15 which is adapted to be eleQ- 9,

I the carriage and bed, may be of any suitable or preferred construction.

To support the working parts of the ma chine and to make the frame light and at the same time very strongyand to provide a serviceable machlne aswell as one particularly adapted to be transported easlly, I

i provide a frame 22 in which the sides 23 and rear part 24 are made of a single piece of sheet metal- As shown, the frame at the .rear port-ion 24. is provided with two grooved portions 25 and 26. forming two curved inwardly-extending ribs 27, and these ribs are eachprovided withapertures 28. which are stamped by means of d es or otherwise formed, and which serve as means through which screws 29 may pass to engage the base of brackets 30, the latter forming ivotaland supporting means for the type-fars13, The frame is provided with a flange 31-; along its upper ed e and with a' flange 32'along its lower e go, both of which flanges are inturned. The upper "'iflange is rounded for a part of its length and'said flanges as well as the ribs 27 serve as strengthennlg means and at the same time the flanges give a substantial appearance to At each corner of the frame and at the pear thereof are two integral extensions or parts 33 and 34, the former of which. ro- 'ects inward from one of the sides 23 o the iFrame, and the extension33 from the rear cpa'rt 24 of the frame. These parts overlap 3 and each have an opening 35 stamped or iformed therein, and fittingathese openings -'at each side thereof is a b sliing or thimble 36 serving as a rivet to ho d the two extensions at each corner together and as a guiding means for one of the vertically movable bars 19 of the shift mechanism. The lower rearcorners of the frame, Figs. 1 and 6, have extensions or lugs 35 and 36*,and these lugs overlap and project from the lower flange 32 and are" riveted or otherwise held together, thus strengthening the frame at this point. By providing the overlapping extensions at the corners to serve as guiding the downward movement of the spacing bar 37", the latter having a bracket or brackets 3 37 secured thereto or other means provided which s adapted to engage said extensions 37 when the bar 37 is depressed, said spacing bar having levers 37 which are su ported in any suitable manner to operate t e uni\*ersal bar ofthe escapement mechanism. The transverse bar has its endspgovided with lugs or projections 38 which fit over' an integral projection 39 forming a part of the lower flange 32 of each side member, the

said lugs 38 and 39 of the frame and the transverse bar 37 being riveted or otherwise held, as desired. The transverse bar 37 may be provided with flanges 40-at its ends serving as further means to securely hold said front piece or bar, 37 to the side members. The frame is provided with a curved portion 41 extending downward from substantially the 'central portion thereof, and

this curvedportion terminates in a concaved portion 42 located above'the transverselyextending. bar 37. This concaved portion 42 serves as a seat or rest for the platen 18, shown in dotted lines in Fig. 1, when the platen and carriage are folded into compact relation with respect to the keyboard. An

intermediate bar 44, also of sheet metal, ex-

tends transversely of the machine, between therear part 24. and the front piece 37, and the flange 31 is cut away to provide two slots 45 and 46 into which tongues projecting from the ends of the bar 44 are adapted to fit, and which hold the bar properly between the said side members. The transverse bar may be provided with other fastening means, if desired, but ordinarily the slots 45 and 46 serve to properly hold the bar in position: Both bars 37 and '44 may be of any suitable shape, and instead of making the frame curved at its upper edge between the bar 44 and the rear. part 24, it may be made straight and the part 42 may be also straight instead of concaved.

A bar 47 is locatedintermediate the rear loo and front portion of the machine and is of the frame. The bar is angular inform and has a flange 48 provided with a plurality of apertures 49 to whichone end of each spring 50 may be attached, the other end of said spring being attached to one ofthe key-levers. The bar 47 is provided with an integral guiding portion 51 extending upwardly therefrom and this guiding portion has two side flanges 52 and a slotted portion 53, Fig. 8, which serves as a pivot for the space-bar levers 37", the said levers being guided in the slots and being notched to fit over a portion of the bar 47 so as to form substantially a knife-edged pivot therefor. a i

At the rear part of the frame, the lower flange 32 is formed with-an extended portion which is bent downward, as at 54, and is provided with an aperture through which passes a bolt 55. This bolt 55 is'provided with a nut 56 at one end and its other end is'attached to one end of a sprin 57, the

. other end of said s ring being he d to the compensatefor the weight of the carriage arm 58 extending tending normally to raisethe inner end of the shift lever and carriage, to partly and parts shiftable therewith. The extensions or parts 33 are each provided with a downwardly-extending portion 59. The

portions 59 each have an aperture 60, which .SEI

pivoted bell-crank levers 60form1ng a part be formed by dies or otherwise,. and portions serve as supports to which are of an escapement mechanism. Each bellfcrank lever has one end thereof operatively connected to rock arms 60 forming a part of an escapement-frame. This frame has a *trans'verse bar which is adapted when moved ward fromthe universe bar 60 the latter being operated by the key-levers and the chines This mechanism is not claimed herein as it is substantially the same as d1sclosed inmy pending application Serial No.
